MANAGING POWER COMSUMPTION IN A DATA STORAGE SYSTEM

摘要

A method for managing power consumption in a data storage system is provided. The method comprises receiving a first input/output (I/O) request identifying an I/O operation to be performed by a storage device; delaying scheduling of the first I/O request to manage amount of power consumed by servicing the first I/O request; and forwarding the first I/O request to a storage controller associated with the storage device. The storage controller schedules the first I/O request using a scheduling mechanism, and the storage device services the first I/O request according to the scheduling mechanism.
